Convert portrait AI video to 16:9 widescreen via outpainting

Use the supplied video <video 1> exactly as the source and convert it to 16:9 widescreen by outpainting ONLY the missing areas on the left and right sides. Preserve the original video in the center exactly as it is, including the woman, her movement, body direction, pose, timing, camera angle, background, lighting, colors and composition. Do not recreate or reinterpret the scene, do not change the camera angle or make the woman move differently, and do not crop, zoom, stretch or reposition the original footage. Simply extend the existing environment naturally to the left and right to create a seamless 16:9 video. Maintain the original visual quality with no added noise, grain, flicker or warping. No Music.
